ArmPkg/ArmLib: remove CCSIDR based cache info routines
The ARM architecture does not allow the actual geometries of the caches
to be inferred from the CCSIDR cache info system register, since the
geometry it reports is intended for performing cache maintenance by
set/way and nothing else. Since the ArmLib cache info routines are
based solely on CCSIDR contents, they should not be used.
